IMPROVEMENT IN THlLL-COUPLINGS.

Specification forming part of Letters Patent No. lSl,84S, dated September 5, 1876; application filed August 9, 1876.

To all whom tt may concern:

vBe it known that I, HENRY J. ILES, of the town 0f Seymour, in the county ofNew Haven andState ot' Connecticut, have invented certain new and useful Improvements in Thill- Coupling; and I do hereby declare that the 'ollowing is a full, clear, and exact description thereof', Which will enable others skilled in the art to which it appertains to make and use the same, reference. beingl had to the accompanying drawings, and to the letters ot'ret'erence marked thereon, which form a part of this specitication.

The nature of my invention consists in the construction and arrangement of a thillcoup ling, as will be hereinafter more fully set forth.

ln the annexed drawing, Figure lis a plan view of my invention. Fig. 2 is a longitudinal section ot' the same. Fig. 3 is a perspective view ot' a spring used therein.

A represents the axle, over which the clip B is passed. This clip is at both ends formed with the usual bolts a a, which pass through the bottom plate C, and fastened by nuts b b. At the front end ofthe plate C are forwardlyprojecting ears D D, between which thel thilliron is pivoted by means ot' the bolt d. The ears D D form solid shoulders a: x, against the front side of the axle, and on the rear side ot' axle the bottom plate C is formed with a solidshoulder, y, bearing against the same. These shoulders may extend any suitable distance up both sides otl the axle and take all the strain o from the clip-bolts. The rear clip-bolt a is extended a suitable distance, as shown, and passes through an elongated slot, e, in the rear end of a spring, E, the front end of which is curved upward between the ears D D, and then forward, to bear against the eye of the thill-ron G. On the front end ofthe spring E is fastened a piece ot'leather,f, to prevent the metal ot' the spring from coming in contact with the thilliron. The under side of the spring E around the slot e is beveled, as shown, and a correspondingly-shaped nut, h, is screwed upon the rear bolt a, to fasten the spring. By running this nut up and down on said bolt the tension ot' the spring on the thill-iron is easily regulated, and by the bevelingl of the spring and the peculiar construction ot' the nut, the nut is held from working loose. On the t'ront end of' the clip B are formed shoulders i 1l, for the purpose ot' holding rubber in, when such is desired to be used.

This thill-coupling is simple in construction, and yet strong' and durable., and not liable to get out of order, no rattling ot' vthe coupling,

and the thills may be held in an upright position simply by the friction of' the springs.

I am aware of Patent No. 87,501, dated March 2, 1869, and I do not claim anything shown therein; but

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The spring E, with single slot e, and beveled on the under side around said slot, and the correspondinglyshaped nut lz., in combination with the rea-r clip-bolt, clip B, and plate C, all constructed and arranged as and for the purpose set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two Witnesses.

HENRY J. ILES.
